David Wagner, the manager of Aaron Mooy's club Huddersfield Town, has left his post.
Wagner has exited Huddersfield with the club embroiled in a relegation battle.
The Terriers have lost eight of their last nine Premier League games and sit bottom of the table.
Wagner, who got the club promoted in 2017, has reportedly left the west Yorkshire outfit on good terms.
The German approached the club's owners over the weekend to suggest a change was needed.

"I’d like to begin by thanking David for all he has achieved at Huddersfield Town over the last three-and-a-half years," Huddersfield chairman Dean Hoyle said in a statement.
"Under his stewardship, we’ve achieved things on the football pitch that surpass anything in modern memory, and that have gone well beyond my wildest expectations as Chairman and as a fan.
"Under David’s management, we took this club to the highest position it has held in almost 50 years and created memories that will last forever.
"His achievements will rightly put him up there in Huddersfield Town history alongside great names like Herbert Chapman and Mick Buxton; legendary managers who changed the face of this club."
